Python Tkinter 飞机大战游戏教程：简单易懂的代码示例

用一个简单的飞机大战游戏例子来学习如何使用 Python 3.11 的 Tkinter 库构建游戏。这个游戏包含玩家飞机、敌人飞机、弹击弹击和碰撞检测等功能。

import tkinter as tk

class Game:
    def __init__(self, root):
        self.root = root
        self.canvas = tk.Canvas(root, width=600, height=600)
        self.canvas.pack()
        self.canvas.bind('<KeyPress>', self.on_key_press)
        self.canvas.bind('<KeyRelease>', self.on_key_release)
        self.canvas.focus_set()
        
        self.player = self.canvas.create_rectangle(275, 500, 325, 550, fill='blue')
        self.player_speed = 5
        self.player_direction = 0
        self.canvas.bind('<Button-1>', self.fire_bullet)
        
        self.bullets = []
        self.enemy = self.canvas.create_rectangle(275, 50, 325, 100, fill='red')
        self.enemy_speed = 2
        self.enemy_direction = 1
        
        self.game_over = False
        
        self.update()
        
    def update(self):
        if not self.game_over:
            self.move_player()
            self.move_bullets()
            self.move_enemy()
            self.check_collision()
        self.root.after(10, self.update)
        
    def move_player(self):
        x1, y1, x2, y2 = self.canvas.coords(self.player)
        if self.player_direction == 1 and x1 > 0:
            self.canvas.move(self.player, -self.player_speed, 0)
        elif self.player_direction == 2 and x2 < 600:
            self.canvas.move(self.player, self.player_speed, 0)
            
    def on_key_press(self, event):
        if event.keysym == 'Left':
            self.player_direction = 1
        elif event.keysym == 'Right':
            self.player_direction = 2
            
    def on_key_release(self, event):
        if event.keysym in ['Left', 'Right']:
            self.player_direction = 0
            
    def fire_bullet(self, event):
        x1, y1, x2, y2 = self.canvas.coords(self.player)
        bullet = self.canvas.create_rectangle(x1 + 25, y1 - 10, x2 - 25, y2 - 10, fill='yellow')
        self.bullets.append(bullet)
        
    def move_bullets(self):
        new_bullets = []
        for bullet in self.bullets:
            self.canvas.move(bullet, 0, -5)
            x1, y1, x2, y2 = self.canvas.coords(bullet)
            if y1 < 0:
                self.canvas.delete(bullet)
            else:
                new_bullets.append(bullet)
        self.bullets = new_bullets
        
    def move_enemy(self):
        x1, y1, x2, y2 = self.canvas.coords(self.enemy)
        if x1 <= 0 or x2 >= 600:
            self.enemy_direction *= -1
        self.canvas.move(self.enemy, self.enemy_speed * self.enemy_direction, 0)
        
    def check_collision(self):
        for bullet in self.bullets:
            if self.canvas.coords(bullet) in self.canvas.find_overlapping(*self.canvas.coords(self.enemy)):
                self.canvas.delete(bullet)
                self.canvas.delete(self.enemy)
                self.game_over = True
                self.canvas.create_text(300, 300, text='Game Over', font=('Arial', 30), fill='red')

root = tk.Tk()
game = Game(root)
root.mainloop()

这个游戏界面的大小为 600x600，玩家飞机是蓝色的矩形，敌人飞机是红色的矩形。玩家可以使用左右初箭来控制飞机的移动，按下鼠标左键可以弹击弹击。弹击向上移动并在画布的顶部消失。敌人飞机在水平方向上移动，当到达画布的边缘时会改变方向。如果玩家的弹击打到敌人飞机，游戏结束，并在画布中心显示“Game Over”的文字。
